Through a typology of re-cohabitation experiences, this article examines the mobilization of the family home as a resource in the residential trajectories of young adults. It highlights the relationships maintained with the standard of family support and youth integration, analyses based on representations of young people becoming adults, as well as the understanding of the meaning of parental home at the time of re-cohabitation, and representations of family mutual aid. While these experiences reflect a trend towards normalizing parents’ long-term support for their children, they also reveal the profound inequality of this resource. Indeed, the experiences of re-cohabitation depend on both the material capacities of families, as well as on differentiated models of transition to adulthood, the most positive experiences (“the rebound”, “continuity”) being lived mainly by young people from the middle and upper classes, the most negative experiences (“the return”, “the renunciation”) by young people from the working classes.
